Don't know about Bognor, but Skegness was the resort of choice for Adrian Mole's family.

Alice at the Olympics


The Athletes were much too self-absorbed to notice Alice, but a large besuited figure suddenly boomed: “Young person! Do you do sport? Then you must be obese!”
Alice considered this comment unpleasantly personal, and might have responded by remarking on his own rounded figure, until she realised that the effect of plumpness came from his coat’s being so very well-stuffed with banknotes (which seemed unusual in this Land of Cuts).
“Obese!” he repeated. “Young people just watch television! That’s why we need these Olympical games!”
“So in your games,” said Alice, interested, “obese young people will run and jump, to become thinner?”
“No glory in that!” he snorted loftily. “Athletes run. Athletes jump. Obese people watch them on television.”
“And will that make the young people thinner?”
“Of course! Or we wouldn’t have a legacy. That should be obvious to anyone.”
